p whicheommunicates' with the outlet osport 22fformed in the bottom and 'at the rear of the air casing. Said 'fan, 20, serves-to. expelheated air from the interior .of said casing". -=.This arrangement or a fan .--o1-; supplying the air casing With'fres'h air,- goo-acting witha second fan for removing the heated airgfrom .said' casing causes-a rapid circulation-0i air and cooperates with the water to cool the cylinders. I I

I provide each of the water-jacketed cylinders 12 with a plurality of horizontally arranged flanges-23 which radiate heat from said cylinders and aid materially in coolingsaid' cylinders and the water containedtherein. In order to prevent dead air'spaces between and about the cylinders, battle-plates 24 are arranged between the sides la -of the casing and alternate engine cylinders 12. These plates direct the main currentof air in out between said'cylinders as indicated by arrows in. Fig. 1 of the'drawings. A part of the current of air produced by the 'fans 19 and passes between the flanges 19 of each cylinder 12- and the adjacent ba'lileeplate 24} This supplementary current of air, together with the maincurrent, constantly supplies-'thee'ntire peripheries of the cylinders 12 and .flanges23 with rela- ,tively cool air. Afg'fseri'es ofperforations 25 is tormedon theQ-Tedge of each QL'Qadjacent. to the "side wall 14* of the easing 14* andis arr'ganged to permit the passage. of air througli said bathe-plates to further eliminate dead air spaces in the pockets between the sides of the casing and backs of the battle-plates 24-.

' vMy improved system permits the use of a relatively small volumeof water. and thereby cheapens construction and eliminates unnecsary weight. i

Having described my invention what I Patent is:

1. The combination, with a combustion engine having a plurality of cylinders ingclosed withinan air casing and provided with anair inlet passageway atone end and an outlet port-at theother, of a fan adjacent to the inlet passageway, a second fan adjacent to said outlet port, said fans being adaptedto cause a circulation oi air through said casing, and baffle-plates within the easing extendin irom the sides thereof to alternate cylin 'ers bathe-plate claim as new and desire. to protect by Letters of said engine for directing the current of air between and about said cylinders and from one side of the casing to the other. I p

2. The combination with a combustion engine having a plurality of cylinders and inclosed within an air casing provided with an air inlet passageway at one end and an air outlet port at its other end, of a plurality of horizontal flanges on each of said cylinders, a fanadjacent to said inlet passageway and a second fan adjacent to said outlet port, said fans being adapted to cause a circulation of air through said air casing and perforated baffle-plates within the casing extending from the sides thereof to alternate cylinders of said engine adapted to divert the main current of air from one side of the casing to the other and to permit a lesser current of air to pass directly through said casing. a

3. The combination with a combustion engine having a plurality of water-jacketed cylinders in, communication with a source of water supply and inclosed within an air casing provided with an air inlet passageway and an air outlet port, of flanges'on said cylinders, a power driven fan adjacent to the inlet passageway, a second power driven fan adjacent to said outlet port and bathsplates within the casing extending from the sides thereof to alternate engine cylinders, said fans being adapted to cause a rapid circulation of air through said casing for cooling said source of water supply and said cylinders.

at. The combination with a combustion engine having a plurality of water-jacketed cylinders in communication with a source of water supply and inclosed within an air casing provided with an air inlet passageway and an air outlet port, of a power driven fan adjacent to the inlet passageway, a second casing beneath said hood and communicating with said outlet port, a second power driven fan in said casing andbaltleplates within said fir-stmentioned casing extending from the sides thereof to alternate engine cylinders, said fans beingadapted to cause a rapid circulation of air through said casing. I

5. The combination with. a combustion enginehaving a plurality'of water-jacketed cylinders in communication with 'asource of water'supply and inclosed within-an air casing provided with,an air inlet passago- 5 way at one end and with an air outlet port at its other end, of a plurality of horizontal flanges on each of saidcylinders, a fan a djacent to said inlet passageway and: soc- 0nd fan adjacent to said outlet port,'sai d fans being adapted to cause a circulation of air through the casing and perforated baflleplates within said casing extendin from of said casing, an outlet port at the opposite end of said casing, a fanadjacent to said inlet passageway, a second fan adjacent to said outlet port, said fans being adapted to cause a circulation of air through the ,asing and perforated baflle-plates within said casing extending from the sides thereof to the flanges of alternate cylinders of said engine, said plates being adapted to divert the main current of air from one side of the hood to the other and to permit a lesser current of air to pass directly through said perforations and between said plates and cylinders. v

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
